That’s a great solution! Using a spare phone connected to the port all the time keeps everything charged and ready to go.
Are you paying for a separate data plan for that, or are you using wireless tethering from your main phone?
I don’t make any payments. The phone was free, as was the limitless line.
Is it a family plan that allows you to have as many devices as you like? Who is your supplier? I might have to see if I can acquire that.
I have a T-Mobile family plan with 12 unlimited voice lines and 3 mobile Internet lines, plus about six promotions for free service. Since I have six payers, my costs are very low, and my bill has actually been negative for about three years. The line in the Maverick is a duplicate SIM, so it has data and can make calls while appearing as my primary line.
The only way to snag these promotions would be to time travel!
Good luck 
I am anticipating the release of AAWireless 2. It should be available by the end of this month, I believe. Like you, I have version 1 in our other car, and it functions flawlessly. I appreciate that they update the software so you can be sure it will continue to be maintained in the future.
How fast does the wireless bootup and connect to your phone?
Very fast in a matter of seconds. Overall, I am really happy with the AAWireless dongle, it has pretty reliable connectivity aside from a few minor signal interference incidents.
This was something I did around a year ago. Attach the dongle to the dash with something. Disconnects were induced by forceful bumps.
Just use MXSTTLY adapters for Android Auto or CarPlay to avoid all the adapters and tape. I have one, and it works great. It’s worth the extra money to skip the hassle of buying additional adapters or dealing with a complicated setup.
